10/07/2018#0183;#32;The main objectives of mill ventilation are to ensure the cooling of the mill, internals and for dedusting. If temperature of the mill goes above 110 o C due to less ventilation. Dehydration of the gypsum takes place and creates quality problems like false set and low fluidity of cement. It causes coating in balls and liners and reduce the grinding efficiency of the mill.
Mill ventilation is important for cooling the mill, removing moisture and improving mill efficiency. Typically, a velocity across the media of 1m/s is a good target. The challenge is to measure it. Cement producers are required to measure and report to government agencies about the air that flows up the cement mill stack.
Symptoms of operating a ventilation and dust collection system too near its dew point are: 1) Sweating and buildups in duct work. 2) Increased dust collector pressure drop. 3) System ventilation capacity decrease. 4) Mill puffing and/or backspilling. 5) Dust collector bag plugging.

3C Moisture Heating and Cooling Many of us have encountered moisture and moisture related problems, whether we are working with raw, coal or finish grinding mills. When we talk about moisture, we also talk about heating (drying) and cooling mill circuits. Mills themselves generate a lot of heat.
n a cement plant, grate cooler is a basic machine in the calcining cement system, its main function is to make the ripe cement material to next system. At the same time, the grate cooler could offer rotary kiln and decomposing furnace hot air flow...

Mill ventilation Besides limiting both the cooling or drying of the system, an underventilated mill (lt;1m/sec. above ball charge) also offers room for production increase by bringing the ventilation back to its design value of around m/sec. above ball charge. If the dust from mill ventilation is directly mixed into the final
